For over two decades the need for an improved method for transferring dialing information for control purpose through the telephone network was recognized. The traditional method of Dial Pulse signaling was not only slow and susceptible to distortion over long wire loops but also requires a direct current (DC) path through the communication channel. This paper presents a Global System for Mobile Telecommunication (GSM) network based system which can be used to remotely send streams of 8 bit data for control of electrical appliances. Furthermore, this paper used the Dual Tone Multi-Frequency (DTMF) function of the phone, and builds a microcontroller based circuit for appliances control to demonstrate wireless data communication. Practical result obtained showed an appreciable degree of accuracy, repeatability of the system and friendliness through the use of a microcontroller.

The Electronic Data Interchange (EDI) is the exchange of standardized documents between computer systems for business use. The objective of this study is to make Electronic Data Interchange secure to use and to eliminate human intervention in the transfer of data between business partners so that productivity and efficiency can be improved and also promote its usage between two or more trading organizations. This paper provides an overview of EDI by describing the traditional problems of exchanging information in business environments and how the EDI solves those problems and gives benefits to the company that makes use of EDI. This paper also introduces the common EDI Standards and explains how it works, how it is used over the internet and the security measures implemented. The system was executed on both local area network and wide area network after a critical study of the existing EDI methods and also implemented using VB.Net programming language. Finally, an interactive progra...

This paper examines the effects of dropping policies on dropping probabilities for multi-class traffic and compares their performance and support for Quality of Service (QoS). The flexibility of these dropping policies is illustrated with respect to performance parameters and traffic characteristics. The method used for this evaluation is simulation on a model network that carries traffic of different class; realtime and bursty (non real-time) traffic. Results showed that Weighted Random Early Detection (WRED) in conjunction with an appropriate queuing discipline provides better support for Quality of Service of real time applications while Tail Drop supports best effort applications.

Today, information technology (IT) has become a key element in economic development and a backbone of knowledge-based economies in terms of operations, quality delivery of services and productivity of services. Therefore, taking advantage of information technologies (IT) is an increasing challenge for developing countries. There is now growing evidence that Knowledge-driven innovation is a decisive factor in the competitiveness of nations, industries, organizations and firms. Organizations like the banking sector have benefited substantially from e-banking, which is one among the IT applications for strengthening the competitiveness. This paper presents the current trend in the application of IT in the banking industries in Nigeria and gives an insight into how quality banking has been enhanced via IT. The paper further reveals that the deployment of IT facilities in the Nigerian Banking industry has brought about fundamental changes in the content and quality of banking business in...

Data as well as information is the most valuable tools used for academic effectiveness and for the organization to achieve its aim and objectives. Data is very essential and the cognitive means to collect and organize this data cannot be achieved without human intelligence. In the contemporary society, the means for reliability, accuracy, effectiveness and for a better recognition of an organization has to do with the reliable information and the means to which data can be collected and organized for future use and for the effective management of the organization. Data intelligence guarantees the integral and sustainable development in all aspect of human endeavors; Science and Technologyy, Arts and Humanities and in every other aspect of human development, data intelligence serves as the master key for decision making. This paper critically reviews the necessity of data intelligence and its application areas in harmony with the effectiveness of academic and educational institutions...
